When Ronald Craig succumbed after a short illness it came as a surprise, but when a specialist called down to consult declares the death as due to chronic arsenic poisoning it proves even more of a puzzle. There are plenty of suspects: the ex-wife, the reluctant fiance, the governess who doesn’t care for children, the widow of the dead man’s cousin, the attending physician, his sister - each with a motive, and each lacking an alibi. There are plenty of clues as well: footprints in the garden, the curious tea, the torn wrapping of the package never sent - to name but a few. All in all, quite a tangle. No wonder then that Chief Constable was only too happy to turn the investigation over to Chief Inspector Pointer of Scotland Yard who fortuitously was in the neighborhood on another matter. But will even Pointer be able to find the way to the truth?
